摘要：The invention relates to a high-pressure seal (1), especially for fuel injectionvalves, for sealing a borehole (4) provided in a body (3). The high-pressure seal (1)comprises a sleeve (9) provided with a profiled element at least in sections on an outerside. The high-pressure seal (1) comprises a sealing bolt (11) having at least one blindhole (19) and a compression element (12). The sleeve (9) is inserted into the borehole (4)from a first side (6), the sealing bolt (11) being introduced into the sleeve (9) from asecond side (7) opposite the first side (6). An outer diameter (c) of the compressionelement (12) is larger than an inner diameter (b) of the blind hole (19) of the sealing bolt(11). The compression element (12) is pressed into the blind hole (19) of the sealing bolt(11) such that at least one form closure is formed between the profiled element (14) ofthe sleeve (9) and the body (3) in the region of the borehole (4). A collar (18) of thesealing bolt (11) is pressed at least indirectly against the body (3) on the second side (7).
